IMPROVEMENT IN KNITTING MACHINERY.

Specification forming part of Letters Patent No. 41,38 I, dated Jannrary 26, 1864.

To all whom it may concern.--

'Be'it known that I, LUKE KAv NAceH, of Waterford, in the county of Saratoga and State of New York, have invented a new and useful Improvement in Knitting-Machines; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure Us a vertical section of a rotary burr, and the parts by which itis attached to the'knitting-machine. Fig. 2 is an elevation at right angles to Fig. 1.

Similar letters'of reference indicate .corresponding parts in both figures.

-This invention-relates to the rotary burrs used in knitting-machines, both as sinkers and-for landing and casting 011' the loops. The

stock or hub .of the burr has heretofore been made with a hole in the center and fitted to rotate on a fixed stud, and has not only required a very frequent application of oil for lubrication, but the oil, having been applied above, has run over the exterior of the burr and injured the work.

The invention consists in securing the hub or stock of the "burr to the stud, and fitting teeth. The stock'lk is firmly secured to the.

central stud or spindle, B, which is fitted into a steel-lined socket, C, formed upon the sup-' v portin g-plate D.

isv an oil fountain or reservoir formed v upon or attached to the plate D, and having a passage, b, leading from itsbottom to the bot- ;tom of the socket .0. I

upright face of the bracket G by means of a screw-bolt, c, which passes through a slot, (1, in

the upright portion of the bracket and screws into a tapped hole in the standard H. The

slot d permits the plate D to be raised and lowered to vary the height of the burr, and

also permits the standard to be turned in a vertical plane to adjust the angle of the burr. What I claim as my invention, and desire to secure by Letters Patent, is

The combination of the stud or spindle.B, secured .in the stock orhub of the burr, and

the socket-bearingG, supplied with oil from the bottom by a reservoir, E, or'other means, substantially as herein described.
